To all whom it may concern:

Be it known that I, FRANK R. Honor, a

citizen of the United States, residing at ing Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to concrete building construction.

In this application, the invention is illustrated and described as applied to the construction of a grain elevator containing a plurality of vertical bins.

lhe primary object of the invention is to economize in the amount of lumber or other material used for supporting the molds used for forming the Walls and which molds are carried upward as successive stages of said walls are constructed. Heretofore, it has i been necessary to run up scaffolding or supports for the molds all the way from the bottom or ground. In a large building this consumes a vast amount of lumber which is practically wasted as it is usually broken in dismantling or taking it apart. If this scaflolding can be dispensed with, it will,

therefore, amount to a very considerable.

saving in the expense of erect-ing a building. This saving in material and expense is possible by employing my present invention which contemplates the use of two sets of uprights which are supported upon pins or bolts molded into the concrete and which are raised alternately one above the other as the work progresses. Certain of these upright-s are placed within each bin or compartment to hold the inner walls of the molds, whileothers'are arranged on the outside of the building for supporting the outer walls of the molds. Devices hereinafter described are employed for bracing the uprights and holding them in true vertical alineinent. Working and safety platforms are also used both within and without the structure, and are adapted to be raised successively to keep u with the molds.

Theinvention a so consists in the features of construction and'combinations ofparts metal uprights used for molding the en,-

-tion: Figure l is a broken plan view of-a portion of a grain elevator in course of erec-'- tion, showing how my invention is used. Fig. 1 is a broken detailed view showing more distinctly one of the blockswhich is nailed to an upright for supporting the working platform. Fig. 2 is an elevation of a portion of the lower part of the structure showing the two sets of uprights usedfor holding the inside molds in place,this figure being designed to show the first stage 0 the construction of the walls.

Fig. 16 is a detailed sectional view showing a modified construction of uprights'for use on'one of the outer corners of the building in connection with metalmold-- walls. Fig. 17 is a detailed perspective view of one of the V-shaped brackets adapted to engage two adjacent interior uprights and connect by means of a bolt with one "exterior upright. Fig. 18 is a broken eleva-' tion of a portion of the outer wall of the building showin how the exterior platforms or scaftol s are secured to the Wall and also how the uprights are heldin place, and Fig. 1 9 is a broken detailed 'elevationof one of the brackets for supporting said extes rior platforins. 4

It should be understood that in the construction of a building of the character described, no matter what its size may be, the forms or molds and uprights for supporting the same are raised all over the structure after the casting of'each section of concrete so that the work is always on the same level which rises ste by step from the foundation until the top 0 the walls of the'building are finished. 1 I

While I have illustrated my invention as i' applied to a grain elevator, it will be under- "stood that it may also be employed for build of bins. 1

- As the forms of molds and supporting uprights used in each of the interior bins or compartments are substantially alike, it will suflice to describe the apparatus and method of .cpnstruction used for erecting the walls 'of one .of said interior bins which will nece'ssarily include the adjacent parts of the r forms, etc., arranged in the. four surround mg b ns. In the same manner, a descrlption,

of the construction of one of the exterior bins, that is those arranged along the outside wall of the building, will also be sufli cient to explain the construction of all of them, except that it will be necessary to point out some features of difference which occur in the formation of the four exterior binswhich are arranged at the corners of the elevator. The descriptionof the con- .struction of the exterior bins will include the mold-walls used on the outside of the building and the devices employed for holding them in place as well as the means for supporting the workmen on the outside of the structure. After the description of each of these two main branches of the case, the modifications relating thereto will be taken up and explained.

Referring first, then, to Figs. 1, 1 2,2,

:3, 3 ,4, 5 and 6 and particularly to Figs.

1 2', '2, 3, 3 5. and 6*, two sets of four uprights 1 are used in each bin or compartment. Each of said uprights is preferably eight feet long and is generally'square in 1 cross-section but has its outer corner flattened'as at 1. The-inner faces 1 of-each upright are grooved or recessed ldngitudinally at l" to receive splines 2 against which the inner mold-walls 3 abut whereby the surfaces of saidwalls which are presented to the concrete are flush with the outer faces 1" of said uprights. Said moldwalls are held in place by tie-rods 4 extending across the bin in both directions. Said moldfwalls are preferably made in sections tw eet in height extending across between t w I adjacent uprights, and three of themi are generally used, one above another, at ,each side as shown inFig. 2 At the beginning of the work, however, only one section is placed at each side for molding the first two feet of wall, see Fig. 2. As illustrated in this figure, at the commencement of'the, opera tion of building the walls, the uprights are set up, the lower set resting upon the foundation 5 with their bottom ends engaging pins 11 in said foundation and the other set placed upon the upper ends of said lower setand secured thereto by overlapping splines 6 arranged in the grooves 1 and fastened by bolts 7 shown best in Fig. 6 It will, be observed that the erection of the uprights in the adjacent compartments will bring said uprights into groups of four which are tied together by spacing blocks 8 inserted at suitable intervals and secured by bolts 9, see Figs. 5 and 2 as well as Fig. 2. The upper ends of the higher set of uprights in one group are connected together and spaced'the proper distance apart by horizontal strips 10 engaging pins 11 removably inserted in the ends of the higher uprights. These stri s 10 may be made in separate pieces as i lustrated in Figs. 2

and 2 or continuousso as to extend over When raised to a higher level.

eeaoso face and the inside corner thereof. Three such holes are shown in each upright, one neaneach end and the other at about its center,'but the number and location of said holes may be changed if it should be found necessary or desirable. Metal pins 12 are inserted into these holes so that they project into the mold and will .be cast into the concrete. It is obvious that when so cast into the body or wall of concrete, and the uprights are removed, portions of said pins will be left projecting from the Wall which are capable of supporting said uprights After the uprights are in place and braced as just explained, a single two-foot section of moldwall is put'in place at each side and restingon the foundation, the edges of said sections abutting against the splines 2 and being held inplace by the tie-rods 4. Then, after two feet of concrete has hardened in the mold,

-two more sections of mold-wall are placed upon the one already in position thereb running the mold up to six feet in heig t, as

' shown in dotted lines in Fig. 2. The working platform 13 is next adjusted on or near the level of the top edge of the uppermostmold-wall-section, said platform being supported on blocks 14 nailed to the uprights, as best illustrated in Fig. 1*. Four feet of concrete is then cast bringing it up to the top of the mold-wall and making in all six 7 feet of concrete wall. After this has set, the

.tions.

working platform is raised and the two lower sections of mold-wall on each side are taken out, cleaned and moved up above the third section which is left in place. It will be understood that the splines .2 are made in short sections so thatfhose securing each side section may be removed,.when it is'desired to raise said side section, without loosenin the sections above it. The working plat orm, when raised, is secured to the uprights as before at about the level of the top edges of. the then highest mold-wall-sec- Four feet more of concrete is then molded, and, When set, the operation of ,moving up the two lower sections of the mold-wall is repeated, it .being understood that the pins 12 are inserted before the concrete reaches their height. The working platform is made with a loose portion or trap-door 15, Fig. 3. When all three sections. of mold-wall have reached a position above: the: lower sets of uprights, the latter are removed, passed up through the trap door in the working platform and set up above the other set which then becomes the lower set. Before the uprights brought from beloware placed in positlon, the strips 10 andpins llm'us be removed andthey are.

subsequentlyput in position on thetops of the raised uprights. It will be" seen that'the repetitions of the operations of raising the mold-wall-sections and sets of uprights will provide for molding'the concrete walls to any height desired and that, after the first set of uprights which rested upon the foundation are removed, the uprights will always be supported upon the pins 12 protruding from the concrete wall already formed, see Fig. 2*, thereby dispensing with the necessity of having scaffolding of supports built up all the way from the foundation as was heretofore required. In practice, the shifting of the forms is called a change or grand change, the latter term being used when the uprights as Well as the mold-wallsections are raised. What I calla safety platform 16 is always supported upon pins 12 a suitable distance below the working platform, as also shown in Fig. 2 ,.and not only serves to prevent the workmen from falling to the bottom of the bin in case they should accidentally slip from the working platform but also to catch particles of concrete which might otherwise pass down to the bottom of the bin. These particles of concrete may be readily removed from the platform, but, if they became attached to the foundation or bottom ofthe bin, it would involve considerable expense to cut them out with a chisel, as would be necessary. 'The safetyplatform may be made just like the working platform but;without the trapdoor. At certain intervals in the building or elevator it may benecessary to construct an enlarged. pilaster, as illustrated at 17 in Figs. 1 and 4, in order to provide an adequate support for the steel framework of the cupola, not shown." To accomplish this the group of four uprights 18 are made larger, that is with broader beveled faces 19 presented to the concrete. Each of these uprights may be formed of two vertical pieces 20, rectangular in cross-sectionjoined by a suitable number of spacing or bracing blocks 21 and planked as at 22 the full eight feet, see also Fig. 6.= One of the pins 11 is preferably placed in each of the Vertical.

In Figs.-7, 8 and 9, I have illustrated certain modifications in the construction of the uprights and' mold -walls. Each upright instead of being made entirely of wood may be faced with sheet metal 23 secured theretoby bolts 23 passed through the wooden backing 24 and engaging lugs'Qh cast or otherwise fastened in .the corner of the fac- &

ing. Said backing is cut away, as at 26, within each edge of the facing thereby forming grooves to receive the stepped edges of the sheet metal mold-wall-section 27. Where an enlarged pilaster is to be molded, the upright-s are each composed of two vertical pieces 28 faced with metal as just described, and sheathed with a single metal plate 29 having its edges formedwith angular flanges 30 riveted to the facings of said vertical pieces. Brackets or ledges 31 are arranged just before the holes for the pins 12 to support and balance the same in horizontal position. Fig. 9 shows an upright having its metal facing. 32 rounded or curved instead of being provided with a square corner. This form may be made of all wood, if desired, and is designed for forming rounded interior corners instead of sharp angular corners in the bins.

In Fig. 13, 8 designates a bolt which may be placed between contiguous uprights for drawing them against the spacing blocks. In the same figure, 2" are metallic splines which may be used in lieu of the wooden splines 2 already described.

As previously stated, in order to mold the bins arranged along the outside of the elevator or building, it is necessary to provide external. mold walls 42 and employ some means for supporting and bracing them in position so that they may also be raised successively like the interior mold-wall-sections.

-The apparatus I employ for this purpose is illustrated in Fig. 1 but is best shown in Figs. 10, 14 and 18. Uprights 33 are erected at suitable intervals and are supported by bolts 34 cast into the concrete in the same manner as the bolts 12 on the interior of thebins. These bolts 34, however, are preferably headed or bent at their inner ends, as

at 35, to prevent them from being pulled out, and they are threaded on their outer ends to receive nuts 36'which clamp upon the outer faces of the uprights. The upper ends of said uprights which extend beyond the concrete are plumbed up by means of adjustable bolts 37 engaging V-shaped brackets 37* each interposed between two adjacent interior uprights, where the outer uprights are arranged intermediate of said inner uprights. Said V-shaped brackets are slotted, as at 37 to allow ready adjustment and removal of the bolts 37. When said outer uprights are in alinement with the inner ones, as at each side of the external pilasters,

single bolts or brace-rods 36*, illustrated in full lines in Fig. 10 areused. The outer mold-walls are further braced, as a whole, by horizontal girders 38 tied to interior uprights by rods 39 preferably provided with turn-buckles 40 for the purpose of adjust- If required, a wedge 41 may be driven in between the girders and the uprights arranged intermediate of adjacent sets of tie-rods 39, which are preferably placed at the sides of the external pilasters, as shown. The external mold-walls are also held by splines 33 fitted in grooves in the uprights 33 similarly to the way in which.

held by splines but are themselves inserted in grooves in the uprights. Brace rods 43 are arranged between the uprights behind said short pieces. These short pieces 42 may be made the full length of the grooved uprights to which they are attached, and may be moved up each time with said uprights.

The external mold-walls are separated from the interior mold-walls-by spacing blocks 44 inserted at suitable intervals. Obliquely arranged spacing blocks 45 are placed between the outside and inside uprights where one of the former comes intermediately of two of the latter, see Figs. 1 and 14.

A peculiarly shaped upright 46 is employed on the outer corners of the structure.

The inner face of this upright is formed with three steps, the middle one 47 of which is designed for forming the corner of the concrete, while the other two 48 supportthe mold-wall-sections. The ends of the horizontal girders .38 extend behind these corner uprights and serve, together with the brace rods 43, to hold said uprights plumb. It will be noted that the provision of the mid dle step 47 insures the formation of a perfectly sharp corner on the concrete whereas, if the mold walls extended all the way to the corner, there would be danger of some of the concrete working between their ends and giving a ragged'appearance to the concrete at the corner.

Figs. 11 and 12illustrate modified forms of exterior uprights having metal facings and adapted for use with metallic mold walls. Fig. 11 shows this modified form of upright used with wooden short wall sections 49 extending across the pilasters, while in Fig. 12, the use of metallic shortwall sections 50 is illustrated.

Fig. 16 is a modified construction of an outer corner upright 51 having an inner metallic facing. and intended for use, in

place of the stepped upright 46, with metallic mold-walls.

To support the workmen on the outside of the building I provide tWu scaffolds 52 similarly constructed and adapted to be alternately raised one above the other up the wall as the same is molded, these scaffoldings being operated in practically the same manner as the working and safety platforms insidethe bins. Each scaffolding is secured upon the bolts 34: by means of nuts placed on the outer ends in the same manner as the outside mold-walls are fastened.
